Question

Обчисліть значення виразу √25-3x,якщо x=3?

Answer 1

$\sqrt{25 - 3 \times 3} = \sqrt{16} = 4$

Answer 2

To calculate the value of the expression √(25 - 3x) when x = 3, you simply need to substitute the value of x into the expression and then evaluate it.

Given x = 3, the expression becomes:

√(25 - 3 * 3)

Now, let's perform the calculations step by step:

√(25 - 3 * 3) = √(25 - 9)

Now, calculate the value inside the square root:

√(25 - 9) = √16

Finally, calculate the square root of 16:

√16 = 4

So, the value of the expression √(25 - 3x) when x = 3 is 4.
